JOHN P. THOMPSON, OF KIRKVILLE, IOWA.

IMPROVEMENT lN WASHING-MACHINES.

Specification forming part of Letters Patent No. 146,489, dated January 13, 1874; application filed December 8, 1873. i

accompanying drawings, which form part of this speciication.

The nature of my invention relates to an improvement in washing-machines; and it consists in the arrangement and combination of parts, which will be more fully set forth hereafter.

The accompanying drawings represent my invention.

a represents an ordinary stool or stand, of

` any desired construction, upon the top of which are secured the two cylinders c d. The larger one, c, in which the clothes are placed to be washed, is provided with a perforated conical bottom7 e, placed just above the mouth of the pipe g, which connects the two cylinders together.' The lclothes to be washed are placed upon the top of this bottom, and are held down by *the perforated cover.1.,vto prevent the water from raising them upward. The smaller cylinder, in which the piston l is placed, serves as a pump-barrel, and into which the water from the cylinder cis alternately drawn, and then forced out again through the pipe g by the movement of the piston. To this piston is attached the pistonrod 2, having cogs upon its upper end, which mesh with those on the operatinglever 3, by which it is pumped up and down. This lever is journaled upon the top of the two sta-ndards 5, which also serve to brace and strengthen the two cylinders in position, and prevent them from being shaken loose while themachine is being operated. The journal -6, upon which the lever turns, has one end made smaller than the other for some distance, so that it can be passed through the standard on that side, as shown by dotted lines, allowing the other end to be withdrawn from its bearing, when the lever can at once be withdrawn and the piston taken out to be either repacked or for transportation.

In replacing the parts, the small end of the journal is passed through the standard far enough to allow the other end to slip into position, when the pivoted stop 7 isturned up over the hole through which the small end passes, and thus the journal is locked in position.

By this arrangement of parts the clothes are washed by alternately drawing the water down and then forcing it up through them again, whereby the clothes `are just as thoroughly cleansed as -by the rubbing process, and without thewear and tear upon them, and the operating parts can be removed and then replaced again without removing a single bolt or screw.

Having thus described my invention, l`

claim- The journal 6, to which the operatingdever 3 is secured, and which has one end smaller than the other, in combination with the standards 5 and stop 7, substantially as shown and described.

j, In testimony that I claim the foregoing I have hereunto set my `hand this 1st day of December, 1873.

i JOHN l?. THOMPSON.
